In another move on building apps and services for Android and iOS instead of pushing their own Windows Phone first, Microsoft is working on a launcher for android, called Arrow launcher.

Arrow Launcher includes three pages. A People, Apps and Notes & Reminders page.

You can download the APK from here http://microsoft-news.com/this-is-microsofts-arrow-launcher-for-android-download-apk/ and request to join the Google+ Beta group here https://plus.google.com/u/0/communities/109393011462139141948 . Seems weird to think Microsoft has a Google+ group page for android software!
